LEONARD ATWOOD, OF NEW YORK, N. Y.

ENDLESS HOD-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 275,455, dated April10, 1883. Application filed January 4, 1883. (No model.)

To all whom. it may concern: v Be it known that I, LEONARDATWOOD, of thecity of New York, in the county and State of New York, have invented acertain new and useful Endless Hod-Elevator, of which the following is aspecification, reference being had to the accompanying drawings,constituting part thereof.

My invention relates to those elevators having continuous motion, andemploying substantially an endless belt or ladder running upon andaround suitable pulleys hung in frames located respectively at the topand bottom of a building in course of erection.

The subjects of my invention area novel carrier or supporter for the hodand its novel combination with the endless belt or ladder, and a novelconstruction ofthe endless belt or ladder itself.

In the accompanying drawings the same letters of reference indicatecorresponding parts throughout the several views.

Figures 1 and 2 are front and side elevations illustrating my invention,and Fig. 5 is an enlarge'd view of the' details. Figs. 3 and at aresimilar views of a modified construction hereinafter more fullydescribed.

Referring to Figs. 1 and 2, upright standards upon any suitable basebear the shafts B and Sin the well-known way. Hand,horse, or steam poweris to be applied in the ordinary manner. The shaft G carries suitablepulleys, I 1, upon and around which travels the endless belt or ladderMM, extending upward to any desired heightover and around similarpulleys, J J, upon the shaft B.

My hod carrier or supporter consists of an X-shaped piece, 0 or 0 upon around of the ladder, as shown in Fig. 1, or between the links of asuitable endless chain, as shown in Fig. 3. This hod carrier orsupporter may be made integral with each round orlink,or may be maderemovable and adjustable upon the round or between the links by any ofthe ordinary mechanical means. The angles may be suited to the angle ofthe hod-bowl,and the arms may be upright or bent outward or forward, asin Figs. 2 and 4, to facilitate removal of the hod and to hold thelowerend of the hod-shank, as shown most clearly in Fig. 2. I prefer tomake the rounds N with a link, a, at each end, as shown in Figs. 1 and5; and when this is made of cast metal I use a wrought link, I),alongside to increase the strength and guard most clearly in Fig.3. Imake it up of single links kept apart by pieces of pipe f fof properlengths, and bolted or riveted together through these pipes.

I adapt and attach my hod carriers or slip I porters O by suitablebrackets or arms, as shown in Figs. 3 and 4., so that they stand outfrom the endless belt to receive the hod-bowl. To givegreater security,a pin or stop, T, may be placed upon the sides of the bowl to preventfalling out.

The manner of using my invention is well knownin the art. I

- What I claim as novel, nseful,'and my invention is- 1. An X-shapedhod-supporter removable and adjustable upon a round of an endlesshodelevating ladder.

2. An X-shaped hod-supporter integral with the round of an endlesshod-elevating ladder.

3. An X-shaped hod-supporter, in combination with a round having linksintegral there with at either end, suited to connect in the parallelchains com posing an endless hod-elevating ladder.

4. A round, in combination and integral with a link at each end, fittedto connect with the parallel chains composing an endless hodelevatingladder. it

5. A wrought link, together with and to reenforcea cast link joined toor integral with the round, as connecting-links of an endlesshodelevating ladder.

6. An endless hod-elevatin g ladder com posed of single links kept apartby pieces of pipe, and bolted or riveted together through such pipes.

7. An X-shaped hod-supporter provided with brackets or arms forattachment to an endless hod-elevating ladder.

.8. An X-shaped hod-supporter outwardly curved or bent to facilitateremoving the hod and to hold the hod-shank against lateral sway.

In testimony whereof I have'hereunto signed my name this 7th day ofOctober, A. 1). 1882, in the presence of two subscribing witnesses.
